Realsched.exe is associated with RealPlayer. This process, also known as RealNetworks application scheduler, is responsible for handling automatic updates as well as update notifications. While an important process, it has been regularly criticized by RealPlayer users for using too much CPU resource both when Windows starts and when Windows is running.

By default this process loads with Windows. If it is slowing the boot process, you can prevent it from starting automatically every time you start your Windows computer.

To remove realsched.exe from startup, complete the following two steps.

Turn off Message Centre

• Locate and click the icon of RealPlayer on the desktop or taskbar
• Click Tools>Preferences>Message Centre>Configure Message Centre
• Deselect all the items that appear in the list
• Save your changes, and close RealPlayer
• Restart your computer

Remove realsched.exe from startup

• Click the Windows icon
• Type msconfig.exe in the Start Search Box, and press Enter
• Click Startup
• Locate and deselect the checkbox before realsched.exe
• Click Apply
• Click OK
• Click Restart (this will restart your computer) or Exit without restart in the System Configuration dialog box that appears on your screen next
